(57) Abstract The invention concerns a sole construction for a sports shoe, comprising a wear sole as well as, be- tween the upper of the shoe and the wear sole, a resilient layer (13). The resilient layer (13) in the sole construction is throughout made of a substan- tially homogeneous material of invariable hardness, in which layer, in the areas of the heel and of the foot arch, perforations (16) have been formed which extend through the resilient layer (13) from the upper to the wear sole so as to produce the desired properties of resilience and attenuation and the de- sired support effect in the sole construction. The perforated area (16), in relation to the area of the resilient layer (13), has been formed largest in the area of the rear part of the heel so as to make the elasticity and the attenuation of the sole construction maximal in this area, whereas, when moving from said area forwards towards the area of the foot arch, the perforated area becomes smaller and the non- perforated area (17) becomes accordingly larger so as to increase the support effect of the sole construc- tion.
